Bryant330l, Do you know something that I dont? Did you talk to Chip and get info that might deter me from using this DA? Talk to me man........ But I have made significant moves within my hanger to acquire and accomodate a DA50 for this plane.

But to answer your question yes I do have a radio that will allow me to change the throttle curve and if needed I can regulate the high end throttle. Im pretty used to flying over powered planes and know very well how to stay out of it. But Ive already got the plane and the DA and Ive sold my Moki 2.10 so Im committed. But in weight comparison of the DA50 to the Moki there is only a few oz's difference. And I know the power and throttle response will be better with the DA50.

And talk to me about that Sledge. Im going to Houston for the Pro-Bro in 2 weeks and I would love to have another Sledge to take with me.

Scott,

The DA thing is purely my opinion. I am sure it will be fine on there, if you like really overpowered planes. I do think I read somewhere that Chip designed this plane for the OS 160, but made it capable to handle a 50 cc gasser. If you can program your throttle curve you will probably be fine. I thought the DA was quite a bit more heavy than the Moki. Not anything new for me to be wrong. I will send you a PM on the sledge.

Not to mention the HUGE savings in fuel... With the DA-50, you can keep the smaller tank (14.2 oz?) and fly with less fuel weight up front and less CG change over fuel time...


The 50 will be simply "insane power" to coin Chip's description. Really beef up the firewall with tri-stock in addition to the dowelling.

Sig Cap 231-EX was 14 lbs with a 1.60 (and pilot) so this plane ought to easily handle the 12.5 lbs...

Bryant does have a point with the throttle curve... Swinging a big, wide bladed 22x10, a couple hundred RPM from a click can pull you out fast. But you'll be able to program a curve and get it where you want it...

Another nice thing is that if and when you tire of the CAP-X (we always seem to eventually) you'll have a SWEET engine for the many 500cc airframes coming to market, airframes that the big OS & Moki's just won't handle...

Good points he makes...... you will have fun with the DA

Ahhh yes.....some very good points. And I researched the weight of these engines pretty good before making my decision to go with the DA. And not that I was ever in doubt of the Moki's ability I guess I just wanted an excuse to own a DA50 and this was it.

You know how we sometime go to great lengths to justify in our own minds our inner most desires. Well all I had to hear was Chip Hyde say that this plane will handle it and that he had flown that setup and approved of it

And the funny thing is that the Sig Cap231ex w/ Moki that I was selling for the money to buy the DA50, I ended up trading for a set of golf clubs. Just another one of wild stretch justifications. But hey.......when I play golf 3 times this year I'll look really good sporting my brand new custom fitted clubs.

Believe me ... you will have more than enough power with that DA-50

I have that engine on a 80 inch GP Patty 300 and fly at half throttle most of the time, and the engine was not broken in ... running very rich. Went straight up anytime I wanted to. I ran a 22 X 10 prop. (good grief ... on a 72 inch plane ???)

Yes indeed .... lack of power will not be an issue. If a 2.8 HP Saito 180 running a 16 X 8 prop will do, I think the 5 HP DA-50 will .... well ... tear up the sky.

Beef up the firewall !!! .... and have fun !

Went out this afternoon and got a couple more flights on mine. did my first harrier landing, not a big deal once I could screw up enough courage to do it. Felt good to finally do one and get it out of the way. Plane does a very nice knife edge spin, winds up with a very fast rotation. Cool and scary at the same time. Inverted flat spins nice, not very fast on the rotation though, flattens out better pulling the sticks to the inside rather than out. My os 160 is plenty of power (18x6w apc, 9000 rpm) but i would not be comfortable with less since you need power to pull out of some of the manuvers this plane will perform. I would be tempted to use the Moki 1.8 if i was starting from scratch since it would take care of the tail heavy problem and give a few hundred more RPM on the same prop. i think the 50cc gas motor might be a little much (I've a DP EDGE on the bench with a ZDZ 50 NG so nothing against gas) but i certainly think the plane can handle it. I would look at beefing the motor box up for the gassers, a close look shows that there isn't a lot there attaching it to the rest of the airplane. Other than that, it should be a blast.
I sure am enjoying mine just the way it is.

take care

I'll be beefing up the firewall for sure. While I understand that the DA is gonna be awsomely overpowering tghis plane I cant help but to think that a 1.8 4-stroker or 1.6 2-stroker will provide anything more than just moderate acceleration. My Moki 2.10 didnt pull very hard on my 13lb Sig Cap231....atleast I thought. Thats kinda why I opted for the DA. Well hopefully somewhere in the next 4 weeks I'll be able to report on it.

Tailspnr, like you I am putting a gasser on this plane, in my case a Brison 2.4. I can tell you this though, a big glow such as a Saito 1.80 or YS 1.40 would make anyone happy jerking it around. My reasons for the gasser are purely economical. My big Saitos burn a ton of fuel and I fly just about every day in the summer. It wouldn't be unreasonable to assume a gallon a day in fuel costs and that adds up quick.

I did talk to Chip about the engine choices for the plane and while he did test the Cap-X with a DA 50, he didn't recommend it, which is why I chose to use the Brison on mine. He said the OS 1.60 or a YS 1.40 would be perfect for it . A gasser will work but the plane wasn't really designed for one as was implied in the original ads. They just put one on it as an expirement. I am planning on pinning the firewall and glassing it as well, in addition i will reinforce the wing saddle area and all of the cross bracing joints in the plane. I suggest you do the same. The RCS 140 or 180 would probably be a good choice of gasser for this plane or one of the MVVS engines, and then hopefully my choice, the Brison. Obviously the DA will work on the plane, as its been done, but I dunno how long the plane will hold up under the stress. Good luck, and let us know how it turns out.

A picture of my fuel tank install.

Also a test to see how uploading an image works.

Tailspnr, I'd be very interested to see the results of putting a DA50 on this plane. Be sure to report how it goes. From my experience with my DP Extra w/ a run of the mill 50cc sachs, total weight close to 16lbs, the power was crazy enough 1 click of throttle was the difference between hovering and pulling out. DA 50 produces even more power yet. I've seen a few videos of DA50s on even heavier planes such as the Kangke Laser2000 and Wildhare Extra special, both planes weighing 17lbs and over, both having STRONG pullouts out of a dead hover.

Chip's video shows a O.S. 1.60 FX whipping the plane around like mad. I guess what I'm getting at is that it seems the DA will be unmanageable power when bolted to this plane. Hope you have good results however!

RW Lewis,

What motor mount is that. It really looks good and a lot lighter than the Du-Bro I am using on my H9 Edge. If you could tell me what make it is and where you got it I would appreciate it very much. [8D][8D]........RJ

It came with the plane....and it is a really nice mount.

I think it is most similar to the Gator soft mount. It's two pieces instead of one like the gator, but the beam extrusions appear to be exactly the same.

Richard,
I can't quite make them out in the pics but, if those are new 5600 series Hitec servos, exercise them at least 20 minutes before commiting to flight. All the ones I've seen go bad do so in the first 10 minutes or so. If they make it that long they should be good to go. I know I'd hate to lose one of these on a maiden flight. A friend gave me the same warning when I installed four new ones on my old GP Giles. One aileron servo went hard over and stayed after about 10 minutes. He had experienced the same thing. I replaced it with another one and never had any trouble.

Thanks for the Hitec Servo info.
I am using 5625 and 5645 servos ... so I will use the test feature of my 9CAP to cycle them.

Seems like a very good idea !

Richard -

What size CF rod did you use for these push rods?.
Which pump are you running?

Plane looks great!

Thx,
Drew

The CF rods are 3/16 with 4-40 ends, JB welded.

The pump is the Perry VP-30. The one that uses crank pressure to power it.

Right now I'm sittin at work. It's 74 degrees out, low humidity, partly cloudy and 5-10 mph wind.....I'm hurtin real bad wanting to fly my Cap again[&o]

Richard

Check this out guys. The ad reads just like the CapX. Event the bit about the covering being tight right out of the box and the aluminum horns.

http://www.rcsuperstore.com/products...aft/eaa232.htm

hmmmm.....It would be pretty easy to tell if it was the same airplane by looking at the motor box/firewall and the unique wheel pants. Ad says 73", but if you go measure your CapX's you'll find they are well under their advertised 74"

BTW - this was an ad link I clicked on in the RCU forum.

Berry berry intersting.......it does appear to have similarities. But I'd venture to guess that Chip's design is exclusive to his builder. I mean Chip did say that he had designed out alot of Cap characteristics right? Now Im sure they would not have gone right out and copied his design and remarketed it.

It doesn't say Chip Hyde on the side like "ours".

Its a different color scheme ....

It cost less therefore can't be the same quality !

It must not be the same Plane !!![8D]

But very interesting.

Nice looking airplane but for the time being an extra 30 dollars plus shipping and handling gets you the Chip Hyde airplane from them.

How do you guys think the supertigre G-3250 would be in this plane? The moki 1.8 weighs 41oz and the super tiger is 43oz but its almost 2.0 cu in and 3.2 horse power. Would that little extra weight hurt it? I bought a new fox 2.4 gasser just for this plane but I'm not sure of the added weight of a gasser and the short wing span might make this plane handle badly. I'm thinking of using the fox in the double vision that is being shipped to me on monday and making the cap glow. I've used super tigre engines and they have always been great. Just not sure what to go with!![&o]
